Gyarados

Mega Gyarados sits at 10.03% usage in singles, ranked 17th, comfortably in the upper-middle tier of the metagame. The Water/Flying typing retains the crippling 4× Electric weakness, but Mold Breaker removes the Ground immunity that wallpapers like Hippowdon rely on, letting Earthquake land reliably. Sets are built around Dragon Dance boosting, backed by Earthquake, Ice Fang, and Waterfall for stable STAB and coverage.

Playstyle：Dragon Dance at 24.9% and Earthquake at 22.9% form the standard boosting-sweeper template, with Ice Fang at 18.5% and Waterfall at 14.4% rounding out the moveset. Mold Breaker is locked at 100%, letting Earthquake ignore Sand Rush, Ground immunity, and similar abilities to smash through physical walls like Hippowdon. Ice Fang patches the Dragon and Ground matchups, while Waterfall guarantees a STAB hit with solid power.

で使用され、純粋な積みエース枠というよりも本技アタッカー兼起点としての運用が中心だとうかがえる。

Playstyle：Protect is effectively required in doubles, and Dragon Dance still appears at 23.3%, showing some users still try the boosting path. Waterfall and Lash Out at 7.4% add priority and STAB pressure, while Crunch at 15.3% covers Dark-types. Earthquake at 1.6% and Power Whip at 1.2% are fringe picks used to patch specific holes.

Single-format usage sits at 1.56%, ranked 68th. Intimidate activates on 98.5% of sets, which alone softens opposing physical attackers, and its Flying typing grants full Ground immunity—a structural advantage that few Water-types share. Offensively it leans on Dragon Dance boosts feeding into 125 base Attack and Water STAB, with Power Whip covering Grass-types that would otherwise wall it.

Playstyle：The standard gameplan is to set up Dragon Dance and clean with Waterfall or Power Whip. Power Whip at 21.3% leads the moveset specifically to hit Hippowdon and Venusaur-type Grass walls—its 120 base power plus Wide Lens at 16.5% coverage helps break dedicated tanks that resist Water STAB. Waterfall at 19.3% provides reliable STAB, Dragon Dance at 13.8% launches the boosting plan. Avalanche (8.1%) and Ice Fang (6.1%) patch Dragon and Ground coverage gaps. Thunder Wave (6.9%) and Taunt (5.3%) offer utility options. After a boost, 125 base Attack overwhelms most uninvested mid-weight targets, though 81 base Speed caps even max Jolly near the 100-stat tier—speed is the structural limit.

Doubles usage is 0.12%, ranked 177th. Its role leans heavily utility—Intimidate support, Thunder Wave disruption, Waterfall for Water STAB—but the support movepool is shallow for the doubles metagame. Against Choice Scarf Iron Valiant, Volcarona, and other fast threats dominating the format, 81 base Speed cannot secure turn order, leaving it on the fringe.

Playstyle：Protect at 21.3% is mandatory for survival, Waterfall at 24% carries Water STAB, Thunder Wave at 11.7% provides speed control, and Ice Fang (8.7%) plus Iron Head (7.1%) fill coverage gaps. Sitrus Berry at 53.7% dominates item choice, confirming a tanky staying-power role rather than a one-shot glass cannon—the bulk investment trades offensive items for multi-turn durability. Adamant 252 Atk/252 Spe at 25.1% is the leading spread, attempting to win turn order, though it still trails anything above 110 base Speed.
